Ahead of the weekend’s New Year’s Eve celebrations, President Barack Obama and his outgoing administration took action against Russia for its alleged election hacking.

The subsequent news cycle found itself populated by viral rebuttals by Vladimir Putin and President-elect Donald Trump, though Obama remained largely silent on the matter. Nor did he publicly say anything noteworthy during the final days leading up to Saturday’s worldwide celebrations.

President-elect Donald Trump, however, not so much. Trump took to Twitter on the morning of New Year’s Eve offer a tongue-in-cheek happy new year to his “enemies” and “those who have fought me.”

All that changed Sunday afternoon when Obama took a page from Trump’s own playbook and took to Twitter to ring in the new year. “As we look ahead to the future,” he tweeted via the official @POTUS account, “I wanted to take a moment to look back on the remarkable progress that you made possible these past 8 years.”
